For many students the library will be highly useful on weekends as they might have an important exam or deadline while their roommates are creating noise in the apartment. I have not come across a library which closes on weekends as so many people need it. I might not have succeeded in explaining our situation well, but if you just keep the library open through one weekend and see the response, then you would be clear about what I have tried to say. If you could not close the library from Saturday afternoon to Sunday afternoon (along with current timings), then it would help me along with countless others. Thanks!
